Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
An origin validation error vulnerability in the Trend Micro Apex One (mac) agent iCore service could allow a local attacker to escalate privileges on affected installations. Please note: an attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The following information is provided as informational only for CVE references, as these were addressed already via ActiveUpdate/SaaS updates in mid to late 2025 (SaaS 2507 & 2005 Yearly Release).

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

This is a local privilege escalation vulnerability in the iCore service of the Trend Micro Apex One agent for macOS. The origin validation error allows a low-privileged attacker who has already achieved code execution on the target system to elevate their privileges to root level by exploiting insufficient validation of request origins in the iCore service.

MitigationApply the security update via Trend Micro ActiveUpdate or ensure SaaS tenants are on version 2507 or the 2005 Yearly Release (or later) to receive the patched agent.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Confirm Apex One (mac) agent is installed
    Check for the presence of Apex One agent files or running processes. On macOS, look for processes named 'Apex One' or 'iCore' using Activity Monitor or running: ps -ef | grep -i 'apex\|icore'
    Affected if The Apex One (mac) agent iCore service is present on the system
  2. Identify installed Apex One version
    Check the installed version of the Apex One agent. Common locations: /Applications/Trend Micro Apex One/ or check via system_profiler SPApplicationsDataType. Also check the iCore service version if accessible via: /Library/Application\ Support/TrendMicro/ApexOne/iCoreDaemon --version 2>/dev/null
    Affected if The installed version is earlier than SaaS 2507 or 2005 Yearly Release (the patched versions)
  3. Verify iCore service is running
    Check if the iCore service daemon is active. Run: ps -ef | grep -i icore or check LaunchAgents/LaunchDaemons for com.trendmicro.icored entries
    Affected if The iCore service daemon is running (required for the vulnerability to be exploitable)
  4. Review iCore service logs for suspicious requests
    Examine iCore service logs for unexpected or malformed requests. Check common log locations: /Library/Application\ Support/TrendMicro/ApexOne/logs/ or /var/log/ for any apexone or icore related log files. Look for unusual origin validation failures or privilege escalation attempts
    Affected if Logs show origin validation errors, rejected requests from unexpected sources, or signs of exploitation attempts

A system is affected if it runs any version of Trend Micro Apex One (mac) agent prior to SaaS 2507 or 2005 Yearly Release with the iCore service enabled.

Mitigation

Apply the security update via Trend Micro ActiveUpdate or ensure SaaS tenants are on version 2507 or the 2005 Yearly Release (or later) to receive the patched agent.
